Revoluční motor? Motor s protilehlými písty i válci (Opposed-Piston Opposed-Cylinder Engine)

Opposed-Piston Opposed-Cylinder Engine

This patented design creates a ground-breaking internal combustion engine family architecture that will run on a number of different fuels, including gasoline, diesel and ethanol. The opoc's new opposed piston-opposed cylinder direct gas exchange operation provides the well known emissions benefit of 4-cycle engines, the simplicity benefits of 2-cycle engines, the power density of the less well known opposed piston engine, and the extraordinary developments in computer and thermodynamics all tied together in a new and proprietary engine architecture. It comprises two opposing cylinders per module, with a crankshaft between them, each cylinder has two pistons moving in opposite directions. This innovative design configuration eliminates the cylinder-head and valve-train components of conventional engines, offering an efficient, compact and simple core engine structure. The result is an engine family that is lighter, more efficient and economical, with lower exhaust emissions. Here you can see this revolutionary engine in operation, which helps to illustrate the simplicity, elegance and compactness of its design.

Advantages:

  • Lightweight with high power density
    • produces more than 1 hp per pound of engine weight
  • Low emissions
  • High fuel economy
  • Simplicity of design for manufacturing efficiency, economy and operating durability
    • 50-percent fewer parts than a conventional engine
    • straightforward assembly
    • no cylinder heads or valve train
    • uses conventional components, materials and processes
  • Inherently low noise and vibration
    • all engine forces counteract each other
    • runs as a fully balanced 4-cylinder 4-stroke engine

Modular Benefits

To meet a wide range of power output needs, these engines can be "teamed" in multiple modules, connected to each other via an electrically controlled clutch. This provides a variable displacement engine that offers significant fuel savings, optimized engine map performance and reduced emissions for real-world applications. Here you can see an engine with a second module added, which will double the power output for larger vehicles, but that can be de-coupled to provide significant fuel savings.

The Engine Family

At this time, EcoMotors International is developing several versions of the opocTM engine, listed below is the topline specifications for the EM100 in a single-module configuration using diesel fuel.
